"I've been hiding my rapidly growing bump while shooting but this kiddo is vying for screen time," the 33-year-old actress, who plays special agent Kate Moretti on TNT's Perception, told the magazine. "We clearly have a future actor on our hands."

Gillies added, "A lot of people are asking whether I'd prefer a boy or a girl. In truth, it doesn't matter to me — I just can't wait to meet little Keanu Robocop."

Both Gillies and Cook star in Gillies' directorial debut, Broken Kingdom, which premieres on Showtime May 15. The second season of Perception premieres on Tuesday, June 25 at 10/9c on TNT. Gillies will reprise his Vampire Diaries role as Elijah for the drama's upcoming spin-off The Originals, which the CW recently ordered to series.
